基于MSP430的温度采集报警系统的设计.doc

摘要毕业设计（论文）PAGEIV10基于MSP430的温度采集报警系统的设计摘要温度控制仪表具有广泛的应用前景,在各种行业中都占有重要的位置，越来越多的领域应用到以单片机为控制核心，用液晶作为显示终端的数字化控制设备，通过单片机对被控对象进行智能控制。本设计是从降低开发成本、扩大适用范围、系统运行的稳定性、可靠性的设计目的出发,采用MSP430F149单片机为控制核心、以单线数字温度传感器DS18B20来完成温度信号的采集、温度以数字的方式显示在LCD1602液晶上，最终实现温度的采集、显示和报警。上下限温度值可以根据实际要求，通过键盘输入来实现设定。从而实现自动温度控制等功能，并重点阐述了系统的硬件构成和软件编程的设计过程。其中硬件构成有六部分：电源及复位模块、采集模块、键盘输入模块、显示模块和报警模块。MSP430F149是一种16位内含FLASH型芯片的单片机，具有高速运算、开发设备简便、可现场编程等特点，这给控制系统的设计带来了极大的便利性。各个模块的电路原理图都有protel来完成。每个模块的软件编程都在IAR开发环境中完成并实现。关键词：MSP430F149，温度控制仪，DS18B20,LCD1602DESIGNOFTEMPERATUREACQUISITIONANDALARMSYSTEMBASEDONMSP430F149ABSTRACTTemperaturecontroltheappearanceofawideapplicationprospect,invariousindustrieswilloccupyanimportantposition,moreandmorefieldstoamonolithicintegratedcircuitstocontroltheuselcdasadisplayterminalequipmentbysomemonolithicintegratedcircuitstocontroltheobjectisintelligentcontrol.Thisdesignistoreducecosts,expandthedevelopmentofthescopeandthesystemrunningstability,reliability,designedbymsp430f149monolithicintegratedcircuitstocontrolthetemperaturesensorandfiguresds18b20tocompletethetemperatureofthecollection,thetemperatureinthenumberofwaysinlcddisplaylcd1602,achievethetemperatureofthecollectionanddisplayandthepolice.Theminimumtemperaturevaluesbasedonactualrequirements,thekeyboardforset.forautomatictemperaturecontrolandotherfunctions,andthehardwareandsoftwaresystemsoftheprogrammingprocess.thedesignofhardwaretoconstituteapartofsixmodules,powerandresetsthecollected,keyboard,themoduledisplaysmoduleand.Msp430f149isa16-bitflashchipsincludingthetypeofoperationofamonolithicintegratedcircuits,thedevelopmentofdeviceeasy,butthecharacteristicsandprogrammingforthecontrolsystemdesignagreatconvenience.allmodulesofaschematicdiagramofacircuitareproteltocomplete.eachmodulesoftwareprogrammingintheiardevelopmentenvironmentsandimplementation.KEYWORDS:MSP430F149,temperaturecontroldevice,DS18B20,LCD1602前言目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc264041903"前言PAGEREF_Toc264041903\h1HYPERLINK\l"_Toc264041904"§概述PAGE
